Benefits of technology

[0015]The ignition voltage is preferably maintained in the form of an ignition pulse for a predetermined duration and is then reduced to the operational voltage. After it has dropped to the operational voltage, a further ignition pulse is then produced if the plasma has not been ignited on all instruments with actuated actuation elements. This measure serves the purpose of safety, to avoid excessive introduction of energy during the presence of the ignition voltage.

Problems solved by technology

This interruption only negligibly disrupts the currently working surgeon because the plasma may occasionally be extinguished anyway if the correct minimum distance required for working is exceeded.

Embodiment Construction

[0021]In the following description, the same reference numbers are used to denote identical parts and those that have an identical effect.

[0022]As shown in FIG. 1, the instruments 301 to 30n comprise hollow bodies with a distally arranged nozzle 32, in whose proximity an electrode 31 is arranged in the hollow body. An actuation switch 33 for actuation of the switches S1 to Sn is provided as the actuation element. The electrode 31, the switches S1 to Sn and the interiors of the instruments 301 to 30n are connected to an instrument hub 12 on the APC device via a connecting lead 34 and an instrument connector 35. From there, the leads are routed on to a high-frequency generator 10, through a valve 15 to an argon source 16 and a control device 11, which controls (open or closed loop) the generator 10 and possibly also the argon source (in particular its pressure).

[0023]The above depiction is merely an equivalent depiction and does not show the exact structure of the known APC devices. I...

Abstract

An APC device to simultaneously operate a plurality of instruments for argon plasma coagulation. In order to enable simultaneous connection and operation of several instruments, the APC device provides several instrument hubs to connect the plurality of instruments and to connect a control device to all instrument hubs. The control device controls the amplitude of a high-frequency voltage and operates the APC device such that, on actuation of at least one actuation means and generation of at least one actuation signal, the high-frequency voltage is interrupted for a defined duration and then the high-frequency voltage is set to the ignition voltage level and, after ignition of the plasma on all of the APC instruments for which the actuation means is actuated, the high-frequency voltage is set to the operational voltage level.

Description

RELATED U.S. APPLICATIONS[0001]Not applicable.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.REFERENCE TO MICROFICHE APPENDIX[0003]Not applicable.FIELD OF THE INVENTION[0004]The disclosed embodiments relate to an argon plasma coagulation (APC) device for operating instruments for argon plasma coagulation.BACKGROUND OF THE INVENTION[0005]APC devices for the operation of instruments for argon plasma coagulation are known, wherein other inert gases besides argon can be used. Reference is made herein only by way of example to WO 93 / 01758.[0006]In large-scale operations, namely when several surgeons are working on one patient, a separate APC device must be available to each of the surgeons to enable him to connect the instrument he is currently using. This is often not possible, not only for cost reasons, but also because it leads to highly constricted space conditions.BRIEF SUMMARY OF THE INVENTION[0007]The object of the disclosed embodiments is to p...
